ASUS A7N8X TwinX CMX512-3200XL

[tpurdy]

I am having real trouble with my motherboard and this Ram. I am on my second batch, "CORSAIR replaced the first set a defective."

I have an ASUS A7N8X rev. 1.04 BIOS 1007, AMD XP3200.

The ram is Corsair TwinX CMX512-3200XL. I am using the user defined settings of, 100% mem. freq., (tRAS):6T,(tRCD):3T,(tRP):2T,CAS Latency:2T

Dim Voltage of 2.7.

 

I can boot all the way to Windows "XP Pro" but then it freezes up every time.

I have tried every slot, and every combination, of either one or both sticks.

 

Each time I get the same outcome. My Bios reads the memory correctly, as 1024 gig's at 200Htz running in dual channel mode. So I don't think this is defective memory. I think I need some other Bios setting options.

 

Please help if you can, these were too expensive not to get working.

Thank you.

Could this be a power supply problem? I am using an N-Spire 420 watt power supply with a WD 80gig HD, CD-Rom ,Cd-Burner, floppy, 4-Port USB2 hub, ATI 9700 Pro card, Audigy2 sound card, USB Printer, USB Scanner.

Please make sure that you have set the jumper settings on your MB from the default 1-2 (133/166/200) to 2-3 (200) FSB only and that you have latest BIOS for your MB and load Setup/Optimized default settings, and try the following BIOS settings;

TwinX1024 or TwinX512-3200XL

CPU Freq: 200 MHz (400 FSB)

System Performance: User Define

Memory Frequency: 100%

Resulting Frequency: 200 MHz (400 FSB)

Memory Timing: User Define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 2T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

DDR Reference Voltage: 2.8 Volts

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

All other settings are motherboards defaults

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!

I ran Memtest 86 last night with all of the settings you sugested. I ran 4-passes on each stick. One of the sticks generates 33 errors, and the other has only 3. I then tried both at once, for 2-passes and received 33 errors and during the 2nd pass the system froze. I also tested the configuation of my 3-sticks of PC2700 kingston running in dual channel. No errors on 2-passes. What should I do next? I am running out of faith. I don't know if "ZIPZOOMFLY" will give me a refund. I have had this product for well over two months now, including the exchange time with Corsair for this batch of new stuff. I would really like to get something to work.

Thanks again for your help. :[pouts:

Have you got a friend with PC3200 that you could borrow? Maybe have him try this memory in his/her board.

 

I am trying to determine if it is the board or the memory at issue, or maybe an issue with that memory and the board.

Please put the modules on DIMM 2&3, and so as the jumper and set the settings with 2.8Volts.
